Hi,

FWIW aerogels are much easier to use than metal cone drivers.
Simple statements about one being better than the other is pointless.

Yes but having used the excel in both passive and active designs, the active one almost identical for the Mag and Aero drivers, I feel I am able to comment on which is better, at least imo.

And of course I agree, the Aerogels are 'easier' to work with. But really there isn't anything hard about a mag cone either, when you know what you are doing. From my stand point, they are both as 'easy' to work with as one another, its just you have to be aware of the limitations of the excels.

Music just floats out of an Aerogel, the Excel feels as if its actually making the music, if that makes sense in any way.

What newer cones are you referring to Taco ?
In the past i've tried Davis (kevlar), Excel (magnesium).
In terms of uncoloured reproduction and effortless dynamics i found the aerogels unbeatable.


Best regards,

I prefere Audiotechnology (mineral filled poly). Also magnesium has more detail (for some to much), but seems not to sound as dynamic. And in most applications it sounds too bright (but it can be done right).

(I have still have 4x HY 170 woofers, waiting to try out).

The aerogels do sound a bit "flat", yes very dynamic but not as resolving. This is my opinion and I do not say these woofers are bad sounding 🙂.

Alex, I don't know those drivers, but it seems a reasonable match. The datasheets are here, if you don't have them already. You might want to open a new thread to discuss your project properly.

The idea of the 0.5 bass driver is to compensate for baffle step, so in this situation it doesn't make sense to run a 2.5 way. It's a better idea to relieve the mid of any bass and make a three way.

The question now of 2 way vs 3 way depends entirely on what you are capable of doing. The three way should sound better, but is more complex to design.

Since there's only one manufacturer that uses aerogel it seems to me we're discussing drivers instead of cone-materials here.
What you end up with depends on the implementation as much as the used material(s).

Considering their price (f.i. Excel-drivers cost almost 2 times as much) and build-quality (excellent) the audax's are top-notch.
What you prefer sonically of course is a personal matter.

Best regards,

The Z6's will be a newer revision of the Z0's, they updated them quite a few times. Nothing major just minor tweaks.

I agree with what everyone has said so far about the Audax's, I used to use HM170Z0's in a 2 way before moving to Scan 18W8531G00's. The Scanspeaks have better and deeper bass, but the Audax's midrange makes the Scan's sound like they are broken.

Where the aerogel's are very dynamic, natural and just plain fun to listen to the Scan's sound flat and boring with fuzzy mid reproduction.
Hopefully adding a 12M4631 to the mix when funds allow will even things up again 🙂

What auxilliary equipment have you used to audition the audaxes/Scanspeaks Fullthrottleric ?

I have compared the audax hm170zo in a 2-way speaker with a dynaudio d-28 as tweeter against the excel 17-cm (magnesium cone, one of the early versions without venting behind the spider) using a ksa-50 driven by a marantz cd72 mkII-se directly (variable output) .

Comparing the audax and the seas, in both the midrange and the low-end, the audax sounded like i was driving a headphone from the power-amp.
Very detailed and completely effortless.

With kind regards,

Klaas

I use them mostly for HT so nothing really exotic, Rotel RDV150E DVD player, RSP 1066 processor and LM3886 chipamps. Although I do have a Zen and Linn LP12 to play with too 😉

Yep I know exactly what you mean, they are a very easy load for amps.

I still think in the bass/midbass area the Scanspeaks are superior, but once you get into the midrange the Aerogel's win easily. I don't think they're the last word in detail but as I said earlier they just sound real and are fun to listen to. Very easy on the ears too, never tiring 🙂

Here is a thread at Parts Express that speaks to, among other things, a replacement for the HM130ZO.

You will probably not find this driver any more. They were superb and those in the know snapped up all available before they disappeared.

You could also try a message posting here:

Perhaps someone will help with a good suggestion for a replacement. Chances are you will have to re-work the crossover to match a replacement driver.

Good luck.........

HM130Z0 replacement

Thanks for the tip, Mr. West. I've been looking for these drivers over two years. A friend of mine built the Dickason A851 about ten (correction-13) years ago and one has a minor dent in the cone (from an accidental poke) and they've picked up a bit of dust and woolie looking things. It all just sticks to those cones. But they still sound decent. I'm having to replace the 210z0s on the bottom (poked a hole in the cone trying to take it out for refinishing the cabinet). I've always liked these speakers. It will be difficult to find a suitable replacement for the A851s.

I'm open to suggestions from anyone.

kind regards,

Nat

Ebay. This is where I've picked up both my pair of HM130Z0's and HM210Z12's. The stuff shows up, I've seen a few pairs of 130Z0's, 170Z0's and a couple of 210Z0 pairs, you just have to be patient and search once every three days or so.

Just make sure to advanced search. display everything from whatever region. I bought the Z12s off a guy in france.

natfin,

The 851 speakers were designed by a famous person. However, this design is rather old. There have been newer models of drivers introduced since then and some more modern thinking about crossover design techniques. You might want to check out the various designs published at Parts Express tech message board. The RS series of drivers are superb and not overly expensive. You might be better of just building a new set of speakers by following the directions in a well received design or kit. Then, you could sell off your extra Audax drivers as they might bring a nice bunch of $$ 🙂
